1 00:00:17,640 --> 00:00:26,560 all right let's uh let's start um so 2 00:00:23,359 --> 00:00:29,720 today I want to talk about uh interest 3 00:00:26,559 --> 00:00:31,399 rates uh you know if you have followed 4 00:00:29,719 --> 00:00:35,238 the news there's a lot of debate on 5 00:00:31,399 --> 00:00:37,280 these days on on on where will the 6 00:00:35,238 --> 00:00:40,679 interest rate in the US end at the end 7 00:00:37,280 --> 00:00:43,679 of this Titan tiing tightening 8 00:00:40,679 --> 00:00:43,679 cycle 9 00:00:46,920 --> 00:00:52,640 uh and um so I'll show you there has 10 00:00:50,799 --> 00:00:54,558 been a very aggressive monetary policy 11 00:00:52,640 --> 00:00:57,600 trying to fight the inflationary episode 12 00:00:54,558 --> 00:01:00,039 we're going through uh and that's done 13 00:00:57,600 --> 00:01:03,280 through interest rates and and the 14 00:01:00,039 --> 00:01:05,239 question that I want to address today is 15 00:01:03,280 --> 00:01:07,118 H well how is it that the interest rate 16 00:01:05,239 --> 00:01:11,000 is determined so when a central bank 17 00:01:07,118 --> 00:01:13,719 decides to hike interest rates how do 18 00:01:11,000 --> 00:01:15,438 they do that okay and obviously this is 19 00:01:13,719 --> 00:01:17,679 about financial markets interest rate 20 00:01:15,438 --> 00:01:19,158 are set in financial markets and 21 00:01:17,680 --> 00:01:21,799 financial markets are very very 22 00:01:19,159 --> 00:01:23,400 complicated so we're going to keep it 23 00:01:21,799 --> 00:01:25,079 very very simple we're want to make 24 00:01:23,400 --> 00:01:26,400 introduce more complexity later on in 25 00:01:25,078 --> 00:01:28,599 the course but still we're going to keep 26 00:01:26,400 --> 00:01:31,320 it pretty simple because our main 27 00:01:28,599 --> 00:01:35,839 objective in studying Financial Market 28 00:01:31,319 --> 00:01:38,199 is really a a to to re to achieve some 29 00:01:35,840 --> 00:01:39,799 sort of understanding of how the 30 00:01:38,200 --> 00:01:43,159 interest rate policy that the Central 31 00:01:39,799 --> 00:01:46,410 Bank H controls is is 32 00:01:43,159 --> 00:01:48,439 determined so before 33 00:01:46,409 --> 00:01:51,560 [Music] 34 00:01:48,438 --> 00:01:54,679 I I get into specifics so let's let's 35 00:01:51,560 --> 00:01:56,799 see some trivia here who knows who that 36 00:01:54,680 --> 00:02:00,439 person is 37 00:01:56,799 --> 00:02:04,240 okay you 38 00:02:00,438 --> 00:02:04,239 Geron Powell exactly and who's Jeron 39 00:02:04,840 --> 00:02:11,159 Powell the chair of the Federal Reserve 40 00:02:08,199 --> 00:02:13,878 uh system in the US which is the Central 41 00:02:11,159 --> 00:02:17,120 Bank of the US okay so that's that was 42 00:02:13,878 --> 00:02:19,000 an easy one and and every you know if 43 00:02:17,120 --> 00:02:20,319 you are into financial markets everyone 44 00:02:19,000 --> 00:02:22,560 is worried about what this guy is 45 00:02:20,318 --> 00:02:24,639 thinking and his friends are thinking at 46 00:02:22,560 --> 00:02:26,239 this moment because they determine the 47 00:02:24,639 --> 00:02:28,518 interest rate how do they do that well 48 00:02:26,239 --> 00:02:32,640 that's what we're going to talk about 49 00:02:28,519 --> 00:02:32,640 later on a little speaker who is 50 00:02:34,239 --> 00:02:38,080 this no no that's that's 51 00:02:38,318 --> 00:02:45,199 cheating katsu WEA he is the next ER 52 00:02:43,318 --> 00:02:49,039 president of the bank of Japan the 53 00:02:45,199 --> 00:02:50,479 Central Bank of Japan and an interesting 54 00:02:49,039 --> 00:02:52,799 there are many interesting things of him 55 00:02:50,479 --> 00:02:54,840 but about him but he's a he's a graduate 56 00:02:52,800 --> 00:02:58,680 from our program the PHD 57 00:02:54,840 --> 00:03:00,878 program which actually is an incredibly 58 00:02:58,680 --> 00:03:04,280 successful program at producing major 59 00:03:00,878 --> 00:03:06,000 Central Bankers Ben Bernan is our Alum 60 00:03:04,280 --> 00:03:09,318 Alum that he was 61 00:03:06,000 --> 00:03:11,239 the the chairman of the Central Bank the 62 00:03:09,318 --> 00:03:14,919 chair of the Central Bank of the FED 63 00:03:11,239 --> 00:03:17,360 during the financial crisis Mario dragi 64 00:03:14,919 --> 00:03:21,439 is a one of our graduates Mario dragi 65 00:03:17,360 --> 00:03:24,000 was the the most successful ER Central 66 00:03:21,439 --> 00:03:27,719 Banker in Europe he was the president of 67 00:03:24,000 --> 00:03:29,120 the ECB European Central Bank for many 68 00:03:27,719 --> 00:03:32,080 years and in particular during the 69 00:03:29,120 --> 00:03:33,438 Global Financial crisis and the European 70 00:03:32,080 --> 00:03:34,799 crisis which followed the global 71 00:03:33,438 --> 00:03:38,519 financial 72 00:03:34,799 --> 00:03:41,319 crisis uh I mean but you name it Stan 73 00:03:38,519 --> 00:03:43,959 Fisher in the past of the Bank of Israel 74 00:03:41,318 --> 00:03:47,639 and nowadays feel low of the the chair 75 00:03:43,959 --> 00:03:50,400 of the Reserve Bank of Australia in 76 00:03:47,639 --> 00:03:52,199 Chile we have had two or three er 77 00:03:50,400 --> 00:03:53,840 presents and so on so if you if this is 78 00:03:52,199 --> 00:03:56,078 your career this is a good program you 79 00:03:53,840 --> 00:03:58,759 should join our program you may end up 80 00:03:56,079 --> 00:04:00,599 in a in a good place but that's the the 81 00:03:58,759 --> 00:04:02,318 next one for Japan 82 00:04:00,598 --> 00:04:04,238 and and Japan is a very interesting 83 00:04:02,318 --> 00:04:06,839 place from the point of view of monetary 84 00:04:04,239 --> 00:04:08,840 policy precisely because they they 85 00:04:06,840 --> 00:04:10,438 haven't had much space to do 86 00:04:08,840 --> 00:04:12,319 conventional monetary policy so they 87 00:04:10,438 --> 00:04:14,280 have had to do lots of unconventional 88 00:04:12,318 --> 00:04:17,199 things from the point of view of what a 89 00:04:14,280 --> 00:04:18,798 central bank typically does but today 90 00:04:17,199 --> 00:04:20,160 we're going to study conventional things 91 00:04:18,798 --> 00:04:22,519 and we'll talk a little bit more about 92 00:04:20,160 --> 00:04:25,560 unconventional things later in the 93 00:04:22,519 --> 00:04:28,399 course now some institutional knowledge 94 00:04:25,560 --> 00:04:29,959 this is the the again in the US the 95 00:04:28,399 --> 00:04:31,959 Central Bank of the US is called called 96 00:04:29,959 --> 00:04:36,839 the Federal Reserve System and it's a 97 00:04:31,959 --> 00:04:39,159 system really H it's a he has a um in um 98 00:04:36,839 --> 00:04:40,719 the Board of Governors which sits in 99 00:04:39,160 --> 00:04:43,400 Washington 100 00:04:40,720 --> 00:04:46,680 DC um and and there are seven Governors 101 00:04:43,399 --> 00:04:48,799 and the governors are are are nominated 102 00:04:46,680 --> 00:04:51,800 by the president and and then confirmed 103 00:04:48,800 --> 00:04:56,879 by by the Senate and the president of 104 00:04:51,800 --> 00:04:59,840 that board is is H is so the president 105 00:04:56,879 --> 00:05:03,439 of the FED of the FED will be one of 106 00:04:59,839 --> 00:05:05,478 those members okay now on in addition to 107 00:05:03,439 --> 00:05:08,360 that the the US has a Federal Reserve 108 00:05:05,478 --> 00:05:11,719 Bank system there are seven there are 12 109 00:05:08,360 --> 00:05:13,600 Regional Banks uh there's one in Boston 110 00:05:11,720 --> 00:05:15,800 in fact if you look at the skyline near 111 00:05:13,600 --> 00:05:19,479 the Waterfront there's a building built 112 00:05:15,800 --> 00:05:23,720 out of recycled aluminum well that's the 113 00:05:19,478 --> 00:05:27,120 Reserve Bank of Boston and uh and uh and 114 00:05:23,720 --> 00:05:30,400 of those 12 Regional Banks they 115 00:05:27,120 --> 00:05:32,120 rotate so so policy the interested is 116 00:05:30,399 --> 00:05:35,758 set into in a committee which is called 117 00:05:32,120 --> 00:05:38,720 the fomc Federal Open Market Committee 118 00:05:35,759 --> 00:05:41,360 um and and the member of that the voting 119 00:05:38,720 --> 00:05:45,199 members of that committee are the the 120 00:05:41,360 --> 00:05:48,720 seven Governors plus h four out of the 121 00:05:45,199 --> 00:05:50,639 12 and they rotate most of them rotate 122 00:05:48,720 --> 00:05:53,759 the the only one I think does not rotate 123 00:05:50,639 --> 00:05:56,918 is the is the is the president of the of 124 00:05:53,759 --> 00:05:58,840 the New York fed because they're so 125 00:05:56,918 --> 00:06:00,359 important because that's a financial 126 00:05:58,839 --> 00:06:04,638 heart of the US 127 00:06:00,360 --> 00:06:06,720 that you certainly want that H ER 128 00:06:04,639 --> 00:06:09,240 president to be involved in in interest 129 00:06:06,720 --> 00:06:11,120 rate decisions and it's really the FED 130 00:06:09,240 --> 00:06:12,960 that is in charge of communication with 131 00:06:11,120 --> 00:06:16,038 financial Market which is a huge thing 132 00:06:12,959 --> 00:06:18,879 for the FED okay they are in New York 133 00:06:16,038 --> 00:06:20,959 and they're crucial for that okay so 134 00:06:18,879 --> 00:06:23,199 that's that's that's those are the 135 00:06:20,959 --> 00:06:26,799 people that and in most places around 136 00:06:23,199 --> 00:06:28,720 the world you're going to have at least 137 00:06:26,800 --> 00:06:31,759 something equivalent to the the seven 138 00:06:28,720 --> 00:06:33,960 governors out there okay most places 139 00:06:31,759 --> 00:06:35,759 obviously the ECB is different because 140 00:06:33,959 --> 00:06:38,758 it's multiple countries so each country 141 00:06:35,759 --> 00:06:41,639 sends one member 142 00:06:38,759 --> 00:06:44,960 no but but but 143 00:06:41,639 --> 00:06:48,639 otherwise um it tends to be like like 144 00:06:44,959 --> 00:06:51,519 the US without the the the regional 145 00:06:48,639 --> 00:06:53,079 Banks so why do we care about monetary 146 00:06:51,519 --> 00:06:54,879 policy well because I think it's one of 147 00:06:53,079 --> 00:06:56,359 the main policy tools you have in the 148 00:06:54,879 --> 00:06:58,918 short run remember in this part of the 149 00:06:56,360 --> 00:07:01,439 course we're trying to understand output 150 00:06:58,918 --> 00:07:03,399 in the short ter and one of the main 151 00:07:01,439 --> 00:07:06,719 policy levels I mean how can you affect 152 00:07:03,399 --> 00:07:08,598 output is monetary policy which one is 153 00:07:06,720 --> 00:07:12,160 the other 154 00:07:08,598 --> 00:07:14,399 one there are two major ones fiscal 155 00:07:12,160 --> 00:07:16,000 policy exactly and fiscal policy we did 156 00:07:14,399 --> 00:07:18,198 look at in the previous lecture remember 157 00:07:16,000 --> 00:07:20,959 we said an expansionary fiscal policies 158 00:07:18,199 --> 00:07:22,680 an increase in G or a decline in t would 159 00:07:20,959 --> 00:07:25,439 lead to an expansion in a great demand 160 00:07:22,680 --> 00:07:27,598 equilibrium output would go out up okay 161 00:07:25,439 --> 00:07:30,240 so fiscal policy is something you always 162 00:07:27,598 --> 00:07:32,560 use in in in deep recessions 163 00:07:30,240 --> 00:07:35,038 uh but monetary policy is much more 164 00:07:32,560 --> 00:07:36,918 Nimble is I mean it's a it's a bunch of 165 00:07:35,038 --> 00:07:38,800 people that need to meet and just change 166 00:07:36,918 --> 00:07:40,198 the interest rate anything that is 167 00:07:38,800 --> 00:07:42,759 fiscal there are some automatic 168 00:07:40,199 --> 00:07:44,400 stabilizers by the way so automatically 169 00:07:42,759 --> 00:07:46,759 fiscal policy becomes more expansionary 170 00:07:44,399 --> 00:07:48,598 during recessions and stuff like that 171 00:07:46,759 --> 00:07:50,840 but any deviation from the typical 172 00:07:48,598 --> 00:07:53,478 automatic stabilizers require Congress 173 00:07:50,839 --> 00:07:55,758 to approve things it's a long process 174 00:07:53,478 --> 00:07:59,598 and so it's not something that can react 175 00:07:55,759 --> 00:08:01,479 as quickly as monetary policy can okay 176 00:07:59,598 --> 00:08:03,000 um so that's what we're going to look 177 00:08:01,478 --> 00:08:04,758 that's that's that's that's the reason 178 00:08:03,000 --> 00:08:07,399 why monetary policy is important for us 179 00:08:04,759 --> 00:08:10,759 at this point then there are medium and 180 00:08:07,399 --> 00:08:12,638 long run issues fiscal policies still 181 00:08:10,759 --> 00:08:14,960 affects equilibrium output in the medium 182 00:08:12,639 --> 00:08:17,400 and long run monetary policies much less 183 00:08:14,959 --> 00:08:19,519 effective at that it's very difficult to 184 00:08:17,399 --> 00:08:21,120 to change sort of equilibrium growth or 185 00:08:19,519 --> 00:08:23,519 things like that with monetary policy 186 00:08:21,120 --> 00:08:25,800 it's going to be pretty minor most of 187 00:08:23,519 --> 00:08:27,359 the impact of monetary policy in the 188 00:08:25,800 --> 00:08:29,680 minum and long run is really on the 189 00:08:27,360 --> 00:08:31,439 price level and inflation more than on 190 00:08:29,680 --> 00:08:33,080 real activity okay but in the short run 191 00:08:31,439 --> 00:08:35,038 it's very powerful for reasons that 192 00:08:33,080 --> 00:08:37,278 we're going to discuss in this and the 193 00:08:35,038 --> 00:08:37,278 next 194 00:08:40,399 --> 00:08:46,639 lecture okay so as I said well monetary 195 00:08:44,120 --> 00:08:48,039 policy acts through financial markets I 196 00:08:46,639 --> 00:08:50,278 I think it's a very 197 00:08:48,039 --> 00:08:52,399 interesting part of my research agenda 198 00:08:50,278 --> 00:08:54,480 is about that is I think is the central 199 00:08:52,399 --> 00:08:57,440 bank is a very strange institution 200 00:08:54,480 --> 00:09:00,240 because most of its mandate are in terms 201 00:08:57,440 --> 00:09:02,600 of what happens in the Goods Market says 202 00:09:00,240 --> 00:09:04,159 you know you don't try not to get into 203 00:09:02,600 --> 00:09:06,800 recession try to get us out of a 204 00:09:04,159 --> 00:09:08,958 recession and so on but unlike fiscal 205 00:09:06,799 --> 00:09:11,159 policy which has tools that are directly 206 00:09:08,958 --> 00:09:12,879 aim at the Goods Market remember it's a 207 00:09:11,159 --> 00:09:14,240 it's a purchases by the government of 208 00:09:12,879 --> 00:09:17,078 goods so if there isn't sufficient 209 00:09:14,240 --> 00:09:18,639 demand for goods the fiscal policy the 210 00:09:17,078 --> 00:09:21,719 fiscal Authority can go out there and 211 00:09:18,639 --> 00:09:23,958 buy Goods that creates more demand the 212 00:09:21,720 --> 00:09:26,519 the central bank is given the same 213 00:09:23,958 --> 00:09:27,679 mandate aside from Price stability and 214 00:09:26,519 --> 00:09:29,399 things like that we're want to worry 215 00:09:27,679 --> 00:09:31,479 about later but it doesn't have any 216 00:09:29,399 --> 00:09:33,000 tools the the the central bank if 217 00:09:31,480 --> 00:09:34,399 there's insufficient demand the Central 218 00:09:33,000 --> 00:09:36,600 Bank cannot go out there and buy 219 00:09:34,399 --> 00:09:38,399 hamburgers right that's fiscal policy 220 00:09:36,600 --> 00:09:41,360 can do that and expand the demand for 221 00:09:38,399 --> 00:09:45,000 hamburgers but not monetary policy what 222 00:09:41,360 --> 00:09:47,159 monetary policy can do is by bonds by 223 00:09:45,000 --> 00:09:49,839 instruments in the financial markets and 224 00:09:47,159 --> 00:09:53,600 through that affects real activity so 225 00:09:49,839 --> 00:09:55,320 the is it's the fastest policy tool but 226 00:09:53,600 --> 00:09:57,200 it's the most indirect in a sense 227 00:09:55,320 --> 00:10:00,360 because it it it has to go through 228 00:09:57,200 --> 00:10:02,480 financial market and and and and that CH 229 00:10:00,360 --> 00:10:05,000 those channels can be very complex but 230 00:10:02,480 --> 00:10:06,879 obviously we're not in the business of 231 00:10:05,000 --> 00:10:09,120 complicating things in this course so 232 00:10:06,879 --> 00:10:11,600 we're going to make it very very simple 233 00:10:09,120 --> 00:10:14,839 we're going to assume that financial 234 00:10:11,600 --> 00:10:16,519 markets only have two instruments 235 00:10:14,839 --> 00:10:17,959 obviously the huge simplification there 236 00:10:16,519 --> 00:10:20,399 are millions of financial instruments 237 00:10:17,958 --> 00:10:22,239 out there but we're going to isolate two 238 00:10:20,399 --> 00:10:23,919 instruments because this happens to be 239 00:10:22,240 --> 00:10:27,360 the instrument 240 00:10:23,919 --> 00:10:30,360 where that that that where the central 241 00:10:27,360 --> 00:10:33,278 banks typically participate 242 00:10:30,360 --> 00:10:36,039 they affect all asset prices around but 243 00:10:33,278 --> 00:10:37,519 the direct interventions typically 244 00:10:36,039 --> 00:10:41,159 recently has been a little different but 245 00:10:37,519 --> 00:10:43,039 typically it's only in this kind of 246 00:10:41,159 --> 00:10:44,600 instruments and so we're going to focus 247 00:10:43,039 --> 00:10:46,199 all of our analysis on on those two 248 00:10:44,600 --> 00:10:49,040 instruments for now later on we're going 249 00:10:46,200 --> 00:10:52,040 to talk about equity and stuff like that 250 00:10:49,039 --> 00:10:55,240 but but just to isolate the the the how 251 00:10:52,039 --> 00:10:57,199 monetary policy works is sufficient to 252 00:10:55,240 --> 00:10:58,440 just focus on two financial instruments 253 00:10:57,200 --> 00:11:02,000 so we're going to assume that people 254 00:10:58,440 --> 00:11:04,959 have their wealth in only two forms in 255 00:11:02,000 --> 00:11:06,000 two Financial assets one we're going to 256 00:11:04,958 --> 00:11:08,000 call it 257 00:11:06,000 --> 00:11:11,320 money and the other one we want to call 258 00:11:08,000 --> 00:11:13,919 it bonds okay 259 00:11:11,320 --> 00:11:15,480 money the characteristic of money what 260 00:11:13,919 --> 00:11:18,599 we call money there are many definitions 261 00:11:15,480 --> 00:11:21,440 of money M1 M2 M3 M4 but let's keep it 262 00:11:18,600 --> 00:11:23,079 very simple money essentially means 263 00:11:21,440 --> 00:11:24,079 something that you can use very easily 264 00:11:23,078 --> 00:11:29,399 for 265 00:11:24,078 --> 00:11:32,359 transactions okay so for example the the 266 00:11:29,399 --> 00:11:34,919 most important example of money not the 267 00:11:32,360 --> 00:11:38,240 largest but the most important one is 268 00:11:34,919 --> 00:11:43,000 Cash currency okay you can buy anything 269 00:11:38,240 --> 00:11:45,919 with cash there no problem whatsoever 270 00:11:43,000 --> 00:11:48,480 now the the the a characteristic that 271 00:11:45,919 --> 00:11:49,838 money typically does not have is that it 272 00:11:48,480 --> 00:11:53,200 doesn't give you any 273 00:11:49,839 --> 00:11:55,160 return you don't invest in cash you know 274 00:11:53,200 --> 00:11:57,560 you have cash because you need to do 275 00:11:55,159 --> 00:12:00,879 transactions but it's not the way you 276 00:11:57,559 --> 00:12:02,759 get a return and so money that's what 277 00:12:00,879 --> 00:12:04,958 it's going to mean for us is something 278 00:12:02,759 --> 00:12:07,240 that is used in transactions but it pays 279 00:12:04,958 --> 00:12:10,599 no interest rate no interest there no 280 00:12:07,240 --> 00:12:12,959 interest on that a bond is going to be 281 00:12:10,600 --> 00:12:14,720 the polar opposite it's going to be 282 00:12:12,958 --> 00:12:18,359 something that pays a positive interest 283 00:12:14,720 --> 00:12:19,759 rate so if you buy a bone for 100 for 95 284 00:12:18,360 --> 00:12:21,919 you're going to get a 100 a year from 285 00:12:19,759 --> 00:12:23,879 now say so you get something out of that 286 00:12:21,919 --> 00:12:26,039 bone but it's not very useful for 287 00:12:23,879 --> 00:12:28,879 transactions I mean you cannot go and 288 00:12:26,039 --> 00:12:30,799 buy your lunch with a bond you get the 289 00:12:28,879 --> 00:12:32,559 piece of B for that and and and many 290 00:12:30,799 --> 00:12:34,919 things cannot be even even within 291 00:12:32,559 --> 00:12:36,679 financial markets you cannot buy asset 292 00:12:34,919 --> 00:12:39,198 with asset you have to go through some 293 00:12:36,679 --> 00:12:41,879 process in which you come sell something 294 00:12:39,198 --> 00:12:43,838 get cash and and with cash you pay for 295 00:12:41,879 --> 00:12:46,879 the other stuff not necessarily cash it 296 00:12:43,839 --> 00:12:48,800 could be other forms of money but but 297 00:12:46,879 --> 00:12:50,679 but typically Financial instrument need 298 00:12:48,799 --> 00:12:53,559 to be sold before you can buy something 299 00:12:50,679 --> 00:12:55,679 else you don't swap them it's not a part 300 00:12:53,559 --> 00:12:59,239 them okay but this is what it means for 301 00:12:55,679 --> 00:13:01,239 us so this whenever you see something 302 00:12:59,240 --> 00:13:04,240 like this is always interesting for an 303 00:13:01,240 --> 00:13:04,240 economist 304 00:13:06,440 --> 00:13:14,160 why and any economies micro economies or 305 00:13:10,360 --> 00:13:16,720 whatever what what have I done 306 00:13:14,159 --> 00:13:18,078 there that makes economics is about 307 00:13:16,720 --> 00:13:22,000 decisions and then it's about 308 00:13:18,078 --> 00:13:22,000 equilibrium okay it's decisions and 309 00:13:22,559 --> 00:13:27,879 equilibrium there's a decision to be 310 00:13:24,559 --> 00:13:29,399 made here there's a tradeoff okay I I 311 00:13:27,879 --> 00:13:31,439 you know if I need to do lots of 312 00:13:29,399 --> 00:13:35,000 transactions I better sort of bias my 313 00:13:31,440 --> 00:13:35,959 portfolio towards cash towards money if 314 00:13:35,000 --> 00:13:38,000 if I don't need to do lots of 315 00:13:35,958 --> 00:13:39,919 transaction then I and the interest rate 316 00:13:38,000 --> 00:13:42,078 is very high particularly then I this is 317 00:13:39,919 --> 00:13:44,360 an issue today today interest rates are 318 00:13:42,078 --> 00:13:47,198 very high nobody care about bonds or 319 00:13:44,360 --> 00:13:49,000 anything you know two years ago when 320 00:13:47,198 --> 00:13:51,120 interest rate was Zero but today 321 00:13:49,000 --> 00:13:52,480 interest rate is 5% so it's an issue 322 00:13:51,120 --> 00:13:54,039 you're not going to if you want to keep 323 00:13:52,480 --> 00:13:56,800 it in cash you're going to give up a lot 324 00:13:54,039 --> 00:13:58,278 of return okay so it's a decision to be 325 00:13:56,799 --> 00:14:00,838 made there a portfolio decision and 326 00:13:58,278 --> 00:14:05,159 that's always interesting for 327 00:14:00,839 --> 00:14:07,839 economies so let's talk about uh that 328 00:14:05,159 --> 00:14:09,360 decision and we're going to talk you can 329 00:14:07,839 --> 00:14:11,120 describe this decision either from the 330 00:14:09,360 --> 00:14:12,320 side of bonds or from the side of money 331 00:14:11,120 --> 00:14:14,240 we're going to describe from the side of 332 00:14:12,320 --> 00:14:16,959 money because there's a total amount of 333 00:14:14,240 --> 00:14:20,159 wealth and you have to decide what to 334 00:14:16,958 --> 00:14:21,599 allocate it to so you know it suffices 335 00:14:20,159 --> 00:14:24,480 if I tell you there a total amount of 336 00:14:21,600 --> 00:14:26,120 wealth and if I tell you how to how much 337 00:14:24,480 --> 00:14:27,240 you allocate to money then I'm telling 338 00:14:26,120 --> 00:14:29,440 you implicitly how much you are 339 00:14:27,240 --> 00:14:31,680 allocating to bonds it's a compliment to 340 00:14:29,440 --> 00:14:33,639 that okay so I can do analysis either 341 00:14:31,679 --> 00:14:36,359 way but I'm going to do it through money 342 00:14:33,639 --> 00:14:38,399 which is the way is normally done so 343 00:14:36,360 --> 00:14:39,720 money demand if I plot it in the space 344 00:14:38,399 --> 00:14:43,399 of 345 00:14:39,720 --> 00:14:45,480 M money and the interest rate is a 346 00:14:43,399 --> 00:14:49,759 downward sloping 347 00:14:45,480 --> 00:14:49,759 curve why is it a downward sloping 348 00:14:51,198 --> 00:14:56,240 curve the interest rate is higher it 349 00:14:54,120 --> 00:14:59,078 pays off more to have B your utility 350 00:14:56,240 --> 00:15:01,399 should exactly your decision if the 351 00:14:59,078 --> 00:15:03,559 interest rate is very high is to go more 352 00:15:01,399 --> 00:15:04,958 towards bone the interest is very low I 353 00:15:03,559 --> 00:15:06,198 don't care too much about bones I'd 354 00:15:04,958 --> 00:15:09,439 rather keep the thing that helps me 355 00:15:06,198 --> 00:15:12,519 transact which is money okay and it's 356 00:15:09,440 --> 00:15:14,839 interesting because for most of your 357 00:15:12,519 --> 00:15:16,078 adult life you have Liv in a world in 358 00:15:14,839 --> 00:15:18,680 which that not was not a very 359 00:15:16,078 --> 00:15:21,078 interesting decision actually no because 360 00:15:18,679 --> 00:15:22,679 interest were very close to zero now 361 00:15:21,078 --> 00:15:25,399 you're living in a different environment 362 00:15:22,679 --> 00:15:28,359 interest Are For the First Time sort of 363 00:15:25,399 --> 00:15:30,720 high for you there may a bigger decision 364 00:15:28,360 --> 00:15:34,159 between invest in equity say and cash 365 00:15:30,720 --> 00:15:36,120 but bonds and and and and these are safe 366 00:15:34,159 --> 00:15:37,719 bonds by the way your treasures and 367 00:15:36,120 --> 00:15:40,198 things like that and money is not 368 00:15:37,720 --> 00:15:43,600 something you have to worry 369 00:15:40,198 --> 00:15:45,198 about okay good what I'm saying is 370 00:15:43,600 --> 00:15:47,399 interest is where around here so you 371 00:15:45,198 --> 00:15:50,399 we're all in cash one way or the other 372 00:15:47,399 --> 00:15:52,198 and now interest are a lot High the 373 00:15:50,399 --> 00:15:53,759 other thing that so that's a movement 374 00:15:52,198 --> 00:15:56,799 along the curve no I'm plotting 375 00:15:53,759 --> 00:15:58,680 something in the space of interest rate 376 00:15:56,799 --> 00:15:59,479 money and interest rate then when I tell 377 00:15:58,679 --> 00:16:01,479 you 378 00:15:59,480 --> 00:16:04,720 what happens when the inter Rises I'm 379 00:16:01,480 --> 00:16:07,480 asking you for a a a movement along the 380 00:16:04,720 --> 00:16:11,240 curve okay I see so if I raise interest 381 00:16:07,480 --> 00:16:12,879 rate I move along the curve up so the 382 00:16:11,240 --> 00:16:14,600 second thing that we have there is 383 00:16:12,879 --> 00:16:16,078 argument we have is something that shift 384 00:16:14,600 --> 00:16:18,319 the curve because it's not part of my 385 00:16:16,078 --> 00:16:20,599 Axis so so it will shift the curve it's 386 00:16:18,318 --> 00:16:24,240 a parameter for each of these curves and 387 00:16:20,600 --> 00:16:26,720 that's nominal income so in particular 388 00:16:24,240 --> 00:16:29,159 if nominal income goes 389 00:16:26,720 --> 00:16:31,278 up I'm showing you there that money 390 00:16:29,159 --> 00:16:32,399 demand goes out meaning for any given 391 00:16:31,278 --> 00:16:33,838 level of interest rate you're going to 392 00:16:32,399 --> 00:16:37,120 demand more 393 00:16:33,839 --> 00:16:38,639 money why do you think that's the case 394 00:16:37,120 --> 00:16:41,198 and again I'm looking here at the 395 00:16:38,639 --> 00:16:43,759 aggregate but but it applies to an 396 00:16:41,198 --> 00:16:43,758 individual as 397 00:16:44,639 --> 00:16:51,680 well so for the same level of wealth now 398 00:16:49,600 --> 00:16:54,319 nominal GDP is 399 00:16:51,679 --> 00:16:58,439 higher remember that nominal GDP is the 400 00:16:54,318 --> 00:17:00,838 same as nominal expenditure here okay so 401 00:16:58,440 --> 00:17:02,120 if GDP is higher then that means there's 402 00:17:00,839 --> 00:17:03,400 going to be more transactions because 403 00:17:02,120 --> 00:17:07,160 there's going to be more 404 00:17:03,399 --> 00:17:09,759 expenditure okay and therefore you need 405 00:17:07,160 --> 00:17:12,480 more of the thing that is use useful for 406 00:17:09,759 --> 00:17:14,640 transactions okay M demand goes up the 407 00:17:12,480 --> 00:17:17,959 second point to highlight is that you 408 00:17:14,640 --> 00:17:20,520 know while in most places I we use why 409 00:17:17,959 --> 00:17:22,240 here I'm using dollar y nominal y why do 410 00:17:20,519 --> 00:17:24,558 you think that's that why why don't I 411 00:17:22,240 --> 00:17:27,959 just put there real GDP rather than 412 00:17:24,558 --> 00:17:27,959 nominal GDP 413 00:17:30,240 --> 00:17:32,679 is the 414 00:17:34,679 --> 00:17:40,679 typo let's go in 415 00:17:37,319 --> 00:17:43,678 steps suppose that prices are totally 416 00:17:40,679 --> 00:17:46,440 fixed and real GDP goes 417 00:17:43,679 --> 00:17:47,720 up that means that this economy needs 418 00:17:46,440 --> 00:17:51,038 more transactions because it's going to 419 00:17:47,720 --> 00:17:53,640 be more expenditure there okay so that 420 00:17:51,038 --> 00:17:56,158 that explains that yeah when real output 421 00:17:53,640 --> 00:17:57,880 goes up then money demand goes up when I 422 00:17:56,159 --> 00:18:00,120 say money demand goes up I said for any 423 00:17:57,880 --> 00:18:04,520 given interest rate we have more money 424 00:18:00,119 --> 00:18:08,239 demand okay now fix real output and I 425 00:18:04,519 --> 00:18:08,240 tell you suppose that the price of goods 426 00:18:08,720 --> 00:18:14,839 doubles do you think you need more money 427 00:18:10,880 --> 00:18:17,120 to transact of course because it's the 428 00:18:14,839 --> 00:18:19,918 same it's equivalent now money is 429 00:18:17,119 --> 00:18:21,599 dollars I have $10 and now prices are 430 00:18:19,919 --> 00:18:24,720 twice what they used to be well I'm 431 00:18:21,599 --> 00:18:26,399 going to need more dollars to transact 432 00:18:24,720 --> 00:18:30,400 okay so that's a reason we have nominal 433 00:18:26,400 --> 00:18:32,159 GDP here rather than real GDP 434 00:18:30,400 --> 00:18:35,640 okay 435 00:18:32,159 --> 00:18:36,600 good so let's now determine the interest 436 00:18:35,640 --> 00:18:39,080 rate and I'm going to do it in the 437 00:18:36,599 --> 00:18:42,359 simplest possible model first and and by 438 00:18:39,079 --> 00:18:44,639 simplest I mean here in particular no 439 00:18:42,359 --> 00:18:49,038 banks no intermediaries okay so there's 440 00:18:44,640 --> 00:18:52,120 only Central Bank and and and and and 441 00:18:49,038 --> 00:18:54,679 people okay so 442 00:18:52,119 --> 00:18:57,119 so suppose that the central banks 443 00:18:54,679 --> 00:18:59,080 decides that wants to this is the way 444 00:18:57,119 --> 00:19:01,319 monetary policy used to be conducted 445 00:18:59,079 --> 00:19:04,879 suppose is the size that it wants to 446 00:19:01,319 --> 00:19:06,439 offer M dollars to the economy and the 447 00:19:04,880 --> 00:19:09,200 central bank is the one that produces 448 00:19:06,440 --> 00:19:13,679 the at this moment which I have no 449 00:19:09,200 --> 00:19:16,279 intermediaries a ER money is really 450 00:19:13,679 --> 00:19:19,880 currency okay the only one that can 451 00:19:16,279 --> 00:19:22,720 produce currency forget Bitcoin only one 452 00:19:19,880 --> 00:19:26,039 that can produce currency is the Central 453 00:19:22,720 --> 00:19:28,839 Bank okay I mean dollars you can no one 454 00:19:26,038 --> 00:19:30,319 else can produce dollars 455 00:19:28,839 --> 00:19:32,038 watch out when we talk about Banks later 456 00:19:30,319 --> 00:19:34,200 on in this economy I'm describing there 457 00:19:32,038 --> 00:19:36,640 are no banks the only one that can 458 00:19:34,200 --> 00:19:38,960 produce Dollars currency is the Central 459 00:19:36,640 --> 00:19:42,000 Bank any other one that produces dollars 460 00:19:38,960 --> 00:19:44,240 that's illegal okay so it's a central 461 00:19:42,000 --> 00:19:45,558 bank so the central bank can decide how 462 00:19:44,240 --> 00:19:48,720 much money to 463 00:19:45,558 --> 00:19:52,158 supply and suppose it decides to supply 464 00:19:48,720 --> 00:19:55,360 M that's it it's a 465 00:19:52,159 --> 00:19:57,600 decision well what is a now for the 466 00:19:55,359 --> 00:19:59,359 first time I can I can answer the 467 00:19:57,599 --> 00:20:02,319 question is well what the interest rate 468 00:19:59,359 --> 00:20:04,599 in this environment why do I know that 469 00:20:02,319 --> 00:20:07,200 because I have a money supply I have a 470 00:20:04,599 --> 00:20:09,319 money demand the intersection at this 471 00:20:07,200 --> 00:20:10,840 level of money supply the equilibrium 472 00:20:09,319 --> 00:20:12,240 interest rate that is interest is 473 00:20:10,839 --> 00:20:15,720 consistent with money demand equal to 474 00:20:12,240 --> 00:20:18,720 money supply is that 475 00:20:15,720 --> 00:20:18,720 one 476 00:20:19,640 --> 00:20:26,440 okay is it clear so I have my money 477 00:20:23,159 --> 00:20:27,880 demand and I'm saying the Central Bank 478 00:20:26,440 --> 00:20:30,080 suppos the Central Bank De size to 479 00:20:27,880 --> 00:20:32,000 supply m well in equilibrium that will 480 00:20:30,079 --> 00:20:34,319 be the interest 481 00:20:32,000 --> 00:20:36,240 rate okay that's the way the interest 482 00:20:34,319 --> 00:20:39,240 rate is 483 00:20:36,240 --> 00:20:39,240 determined 484 00:20:40,240 --> 00:20:45,919 now suppose that the Central Bank 485 00:20:42,839 --> 00:20:48,480 increases remember the the goal of this 486 00:20:45,919 --> 00:20:50,480 lecture is that we get to understand how 487 00:20:48,480 --> 00:20:52,480 is that interest rate is deter is 488 00:20:50,480 --> 00:20:54,400 determined how is that the fed the 489 00:20:52,480 --> 00:20:57,599 Central Bank determines the interest 490 00:20:54,400 --> 00:20:59,519 rate here we said look the Central Bank 491 00:20:57,599 --> 00:21:00,959 decide on certain am amount of money and 492 00:20:59,519 --> 00:21:02,240 then the market determines what the 493 00:21:00,960 --> 00:21:04,880 interest rate 494 00:21:02,240 --> 00:21:07,359 is and this is the way monetary policy 495 00:21:04,880 --> 00:21:09,200 used to be conducted the central banks 496 00:21:07,359 --> 00:21:10,639 would typically decide the amount of 497 00:21:09,200 --> 00:21:13,240 money in the system it was called 498 00:21:10,640 --> 00:21:14,799 monetary Aggregates the amount of money 499 00:21:13,240 --> 00:21:16,359 in the system and then the market would 500 00:21:14,798 --> 00:21:19,519 determine the interest 501 00:21:16,359 --> 00:21:21,879 rate it turned out that that was a 502 00:21:19,519 --> 00:21:24,200 nightmare and so now that's that's not 503 00:21:21,880 --> 00:21:26,919 what central banks do but and it was a 504 00:21:24,200 --> 00:21:29,240 night mayor because this money demand 505 00:21:26,919 --> 00:21:31,200 that looks so peaceful here in practice 506 00:21:29,240 --> 00:21:34,159 is moving around all the time for a 507 00:21:31,200 --> 00:21:36,278 variety of reason you know even holidays 508 00:21:34,159 --> 00:21:38,799 affect the money demand and all that so 509 00:21:36,278 --> 00:21:40,480 so if you fix the monetary Aggregates 510 00:21:38,798 --> 00:21:43,599 and many the man is moving all over the 511 00:21:40,480 --> 00:21:43,599 place what what 512 00:21:44,159 --> 00:21:48,360 happens suppose the Central Bank says 513 00:21:46,519 --> 00:21:50,480 I'm going to offer this amount of M 514 00:21:48,359 --> 00:21:51,719 that's it and now I tell you money the 515 00:21:50,480 --> 00:21:53,000 money is moving all over the place 516 00:21:51,720 --> 00:21:55,960 they're weeks that they have you know 517 00:21:53,000 --> 00:21:58,000 three days of of weekend that have you 518 00:21:55,960 --> 00:22:00,798 know vacations in between or there's a 519 00:21:58,000 --> 00:22:06,000 Super Bowl lots of people decide to buy 520 00:22:00,798 --> 00:22:06,000 tickets or whatever or beer so 521 00:22:06,159 --> 00:22:09,520 whatever well 522 00:22:10,558 --> 00:22:16,839 no because when you say shortage I mean 523 00:22:14,000 --> 00:22:18,240 depends what you mean by shortage but so 524 00:22:16,839 --> 00:22:19,879 so you could be right with that part of 525 00:22:18,240 --> 00:22:22,640 the answer but but when you say exess 526 00:22:19,880 --> 00:22:23,880 theand then I have a problem because 527 00:22:22,640 --> 00:22:25,679 that's true only if the interest rate 528 00:22:23,880 --> 00:22:28,240 doesn't 529 00:22:25,679 --> 00:22:30,159 move but in a in a in a situation you 530 00:22:28,240 --> 00:22:33,919 could just the Central Bank fix M and 531 00:22:30,159 --> 00:22:35,600 let the market do its thing then the 532 00:22:33,919 --> 00:22:37,038 interest rate will not be fixed and 533 00:22:35,599 --> 00:22:39,558 that's exactly the problem that the 534 00:22:37,038 --> 00:22:41,558 interest rate becomes very very volatile 535 00:22:39,558 --> 00:22:44,158 if you if you do it only only through 536 00:22:41,558 --> 00:22:46,759 through monetary arates because this guy 537 00:22:44,159 --> 00:22:47,960 is moving all over the place and so 538 00:22:46,759 --> 00:22:49,919 imagine what happens if this demand 539 00:22:47,960 --> 00:22:52,720 shift up then in equilibrium it say goes 540 00:22:49,919 --> 00:22:55,320 up precisely to avoid your excess demand 541 00:22:52,720 --> 00:22:57,360 no because if this thing goes up I have 542 00:22:55,319 --> 00:22:58,839 an excess demand at that interest rate 543 00:22:57,359 --> 00:23:00,839 but what happen in equili is the 544 00:22:58,839 --> 00:23:04,158 interest rate will go up and so until 545 00:23:00,839 --> 00:23:07,678 the the excess demand 546 00:23:04,159 --> 00:23:10,120 disappears now in in central banks like 547 00:23:07,679 --> 00:23:12,038 the US Central Bank the FED they can 548 00:23:10,119 --> 00:23:13,519 control this stuff fairly well many 549 00:23:12,038 --> 00:23:16,278 other central banks don't have that if 550 00:23:13,519 --> 00:23:18,158 you look at the at the central at at the 551 00:23:16,278 --> 00:23:20,038 Bank of China for example they have lots 552 00:23:18,159 --> 00:23:21,760 of high frequency movements in interest 553 00:23:20,038 --> 00:23:25,200 rate because they not very good at doing 554 00:23:21,759 --> 00:23:27,400 this stuff it's it's not that easy to 555 00:23:25,200 --> 00:23:29,880 okay to to to control an interest rate 556 00:23:27,400 --> 00:23:32,240 for example to keep it we but the 557 00:23:29,880 --> 00:23:34,480 Central Bank used to do that that's what 558 00:23:32,240 --> 00:23:36,640 I'm saying used to do that I'm saying in 559 00:23:34,480 --> 00:23:38,440 practice this system wasn't very good 560 00:23:36,640 --> 00:23:40,799 because this in practice this the man is 561 00:23:38,440 --> 00:23:42,880 moving around for a lot of EOS syncratic 562 00:23:40,798 --> 00:23:44,400 reasons okay some of them are EOS 563 00:23:42,880 --> 00:23:46,559 syncratic some of them are very 564 00:23:44,400 --> 00:23:50,320 predictable there was a lot of panic 565 00:23:46,558 --> 00:23:52,240 around the shift of the year 2000 that 566 00:23:50,319 --> 00:23:54,599 the ATMs would stop working and stuff 567 00:23:52,240 --> 00:23:56,240 like that so it was a massive increase 568 00:23:54,599 --> 00:23:59,278 in money demand because people wanted to 569 00:23:56,240 --> 00:24:01,720 have cash just in case ATMs sto working 570 00:23:59,278 --> 00:24:03,319 okay and and so there are some are 571 00:24:01,720 --> 00:24:05,960 predictable and so but but you can get 572 00:24:03,319 --> 00:24:09,158 very large fluctuations so in practice 573 00:24:05,960 --> 00:24:10,640 what central banks do nowadays is really 574 00:24:09,159 --> 00:24:13,400 is they tell you what the interest rate 575 00:24:10,640 --> 00:24:15,320 is and then they offer whatever M the 576 00:24:13,400 --> 00:24:17,278 market needs for that interest rate 577 00:24:15,319 --> 00:24:19,200 that's the way modern monetary policy 578 00:24:17,278 --> 00:24:21,440 works okay I I'll tell you a little bit 579 00:24:19,200 --> 00:24:25,399 more about that so let's see what 580 00:24:21,440 --> 00:24:29,640 happens here if if if if 581 00:24:25,398 --> 00:24:30,798 uh if the suppose the the Fed 582 00:24:29,640 --> 00:24:32,799 for reasons that you'll understand 583 00:24:30,798 --> 00:24:34,359 better in the SEC in the next lecture 584 00:24:32,798 --> 00:24:37,278 suppose the FED decides that they want 585 00:24:34,359 --> 00:24:40,519 to have an expansionary monetary policy 586 00:24:37,278 --> 00:24:42,480 expansion in monetary policy means it's 587 00:24:40,519 --> 00:24:45,679 going to spand M it was offering certain 588 00:24:42,480 --> 00:24:49,360 amount of M and now it decides to offer 589 00:24:45,679 --> 00:24:51,519 more of the D so what happens in 590 00:24:49,359 --> 00:24:54,038 equilibrium well we start from an 591 00:24:51,519 --> 00:24:55,720 equilibrium here if the interest rate 592 00:24:54,038 --> 00:24:56,759 remains at that level now we have an 593 00:24:55,720 --> 00:24:59,399 excess 594 00:24:56,759 --> 00:25:01,679 supply of money 595 00:24:59,398 --> 00:25:04,959 okay and the only way to restore that 596 00:25:01,679 --> 00:25:07,919 equilibrium is by people demanding more 597 00:25:04,960 --> 00:25:10,558 money and how when will people demand 598 00:25:07,919 --> 00:25:11,200 more money well when the interest rate 599 00:25:10,558 --> 00:25:14,639 is 600 00:25:11,200 --> 00:25:17,000 lower okay so excess demand the interest 601 00:25:14,640 --> 00:25:18,520 start declining then demand for money 602 00:25:17,000 --> 00:25:21,720 starts catching up with a new higher 603 00:25:18,519 --> 00:25:23,038 supply of money okay and you end up with 604 00:25:21,720 --> 00:25:25,558 a lower interest 605 00:25:23,038 --> 00:25:27,759 rate okay so that's an expansion in 606 00:25:25,558 --> 00:25:30,480 monetary policy an increasing M that 607 00:25:27,759 --> 00:25:32,798 leads to a decline in the interest rate 608 00:25:30,480 --> 00:25:35,839 again mod than central banks don't tell 609 00:25:32,798 --> 00:25:37,519 you we're going to increase M by 20% 610 00:25:35,839 --> 00:25:41,359 what they tell you is we're going to cut 611 00:25:37,519 --> 00:25:43,599 interest rate by say 50 basis 612 00:25:41,359 --> 00:25:45,959 points when they tell you that they're 613 00:25:43,599 --> 00:25:47,398 going to C cut interest in by 50 point 614 00:25:45,960 --> 00:25:51,038 they're reading you this 615 00:25:47,398 --> 00:25:53,918 accxes but 616 00:25:51,038 --> 00:25:55,319 behind that operation there must have 617 00:25:53,919 --> 00:25:57,600 been an increase in money 618 00:25:55,319 --> 00:26:00,278 supply and then it comes all the fine 619 00:25:57,599 --> 00:26:02,000 tuning that that they have to do know so 620 00:26:00,278 --> 00:26:03,919 so the interestate remains there when 621 00:26:02,000 --> 00:26:05,919 the man is vibrating around that thing 622 00:26:03,919 --> 00:26:07,679 there but the when we say an 623 00:26:05,919 --> 00:26:11,120 expansionary monetary policy we really 624 00:26:07,679 --> 00:26:13,640 mean cutting interest rates how is the 625 00:26:11,119 --> 00:26:15,959 interest rates cut effectively by 626 00:26:13,640 --> 00:26:17,480 increasing the money supply but they 627 00:26:15,960 --> 00:26:20,880 don't tell you that they are doing that 628 00:26:17,480 --> 00:26:20,880 but that's what they're doing 629 00:26:22,519 --> 00:26:28,079 okay good so nowadays we're in the 630 00:26:26,200 --> 00:26:29,960 opposite process we're moving that way 631 00:26:28,079 --> 00:26:34,038 no 632 00:26:29,960 --> 00:26:35,759 up but you seen in every single meeting 633 00:26:34,038 --> 00:26:39,440 now for the last seven minutes or so we 634 00:26:35,759 --> 00:26:42,000 have seen a hike in interest ratees okay 635 00:26:39,440 --> 00:26:43,120 H well that's they don't tell you that 636 00:26:42,000 --> 00:26:45,919 but they're saying we're going to cut 637 00:26:43,119 --> 00:26:47,879 money supply and moving in that 638 00:26:45,919 --> 00:26:49,799 direction that 639 00:26:47,880 --> 00:26:52,640 direction because if they move in that 640 00:26:49,798 --> 00:26:54,879 direction then interest rate go 641 00:26:52,640 --> 00:26:58,880 up 642 00:26:54,880 --> 00:26:58,880 clear good 643 00:26:59,839 --> 00:27:06,558 what else shifts uh this is different 644 00:27:04,278 --> 00:27:08,720 kind of shift suppose that nominal 645 00:27:06,558 --> 00:27:10,558 income goes up and this is happening all 646 00:27:08,720 --> 00:27:12,200 the time nominal income is growing in 647 00:27:10,558 --> 00:27:14,200 most economies most of the time unless 648 00:27:12,200 --> 00:27:15,840 you're in a recession nominal income is 649 00:27:14,200 --> 00:27:17,080 growing it's growing for two reasons one 650 00:27:15,839 --> 00:27:19,599 because we have inflation and the other 651 00:27:17,079 --> 00:27:22,960 one is because real output is growing 652 00:27:19,599 --> 00:27:25,439 that means that that typically in an 653 00:27:22,960 --> 00:27:26,880 average year manyy demand is Shifting to 654 00:27:25,440 --> 00:27:28,759 the 655 00:27:26,880 --> 00:27:31,278 right okay 656 00:27:28,759 --> 00:27:33,119 so if money demand shift to the right 657 00:27:31,278 --> 00:27:37,200 and money supply does not 658 00:27:33,119 --> 00:27:37,199 change then what happens to the interest 659 00:27:38,398 --> 00:27:43,439 rate money demand goes up money supplies 660 00:27:41,960 --> 00:27:45,000 doesn't change what happens to the 661 00:27:43,440 --> 00:27:48,320 interest 662 00:27:45,000 --> 00:27:51,599 rate increases because at this interest 663 00:27:48,319 --> 00:27:54,798 rate here we have an excess demand for 664 00:27:51,599 --> 00:27:56,678 money so we have to reduce the money 665 00:27:54,798 --> 00:27:58,960 demand how do we reduce money Demand by 666 00:27:56,679 --> 00:28:01,919 increasing the interest rate 667 00:27:58,960 --> 00:28:04,480 that's way we so that's yet another 668 00:28:01,919 --> 00:28:07,559 reason why why it's not a good idea to 669 00:28:04,480 --> 00:28:09,319 be targeting monetary Aggregates the FED 670 00:28:07,558 --> 00:28:12,879 tells you we we want the interest rate 671 00:28:09,319 --> 00:28:14,639 at 5% say okay and then the economy will 672 00:28:12,880 --> 00:28:16,000 be growing and so on and what the FED 673 00:28:14,640 --> 00:28:17,960 will be doing is if they want to 674 00:28:16,000 --> 00:28:19,759 maintain the interest rate at 5% well 675 00:28:17,960 --> 00:28:22,840 they'll keep expanding M so the interest 676 00:28:19,759 --> 00:28:25,480 rate doesn't go up okay that's the way 677 00:28:22,839 --> 00:28:27,678 normally conduct but if the if the FED 678 00:28:25,480 --> 00:28:30,319 stays sleepy and and and you have an 679 00:28:27,679 --> 00:28:33,360 increasing many demand then then the 680 00:28:30,319 --> 00:28:33,359 interest will tend to go 681 00:28:35,480 --> 00:28:44,159 up so I told you that that 682 00:28:40,200 --> 00:28:45,759 ER that the central bank is moving M 683 00:28:44,159 --> 00:28:47,919 increasing them reducing them or 684 00:28:45,759 --> 00:28:50,000 whatever so how do they do 685 00:28:47,919 --> 00:28:52,880 that I 686 00:28:50,000 --> 00:28:55,000 mean it's not that they although that 687 00:28:52,880 --> 00:28:57,278 police has been advocated it's not that 688 00:28:55,000 --> 00:28:59,720 they go in a helicopter and sort of fly 689 00:28:57,278 --> 00:29:02,038 bills on top of all of us they don't do 690 00:28:59,720 --> 00:29:03,960 that although again it has been 691 00:29:02,038 --> 00:29:06,119 advocated in extreme cases of recessions 692 00:29:03,960 --> 00:29:10,319 and so on and it's called helicopter 693 00:29:06,119 --> 00:29:12,639 money just give money away okay 694 00:29:10,319 --> 00:29:14,639 ER but that's not the way it's normally 695 00:29:12,640 --> 00:29:17,600 done for normal operations is not done 696 00:29:14,640 --> 00:29:19,200 that way so how is it done remember that 697 00:29:17,599 --> 00:29:22,879 we have a financial system that is very 698 00:29:19,200 --> 00:29:25,399 simple for now we have money and bonds 699 00:29:22,880 --> 00:29:26,480 so what the Central Bank does the 700 00:29:25,398 --> 00:29:27,639 Central Bank wants to change the 701 00:29:26,480 --> 00:29:29,839 portfolio of people that they want 702 00:29:27,640 --> 00:29:31,759 people to have less bonds say and more 703 00:29:29,839 --> 00:29:33,599 money that's when that's to ruce the 704 00:29:31,759 --> 00:29:36,079 interest rate so what the Central Bank 705 00:29:33,599 --> 00:29:38,158 does is goes up there and expansionary 706 00:29:36,079 --> 00:29:40,119 open market operation open market is 707 00:29:38,159 --> 00:29:44,640 because they go into the open market to 708 00:29:40,119 --> 00:29:46,839 buy bonds okay they as as opposed to an 709 00:29:44,640 --> 00:29:48,240 operation that happens behind doors if 710 00:29:46,839 --> 00:29:50,038 the if the FED went directly to the 711 00:29:48,240 --> 00:29:52,519 treasury and bought bonds that would not 712 00:29:50,038 --> 00:29:54,119 be an open market operation okay but 713 00:29:52,519 --> 00:29:56,599 what they do is they go to financial 714 00:29:54,119 --> 00:30:00,639 their financial system and they go with 715 00:29:56,599 --> 00:30:04,199 a big bag of money and say okay we want 716 00:30:00,640 --> 00:30:08,000 bones and so the public sells bones to 717 00:30:04,200 --> 00:30:10,480 them in exchange for money okay that's 718 00:30:08,000 --> 00:30:13,359 an expansion in market so what we saw 719 00:30:10,480 --> 00:30:15,839 that before when M shift to the right 720 00:30:13,359 --> 00:30:18,240 what the central bank really did is went 721 00:30:15,839 --> 00:30:20,599 out there and bought bonds from the 722 00:30:18,240 --> 00:30:24,200 public the public sold the 723 00:30:20,599 --> 00:30:26,439 bonds and got the cash okay at some 724 00:30:24,200 --> 00:30:27,720 price people when when I show you 725 00:30:26,440 --> 00:30:29,080 equilibrium in the money market that 726 00:30:27,720 --> 00:30:32,120 means also an equilibrium in the bond 727 00:30:29,079 --> 00:30:34,639 market necessarily so it has to be that 728 00:30:32,119 --> 00:30:36,558 the price is right for the for the 729 00:30:34,640 --> 00:30:38,320 portfolio of individuals a 730 00:30:36,558 --> 00:30:40,240 contractionary open market operation is 731 00:30:38,319 --> 00:30:43,319 the opposite is a central bank goes out 732 00:30:40,240 --> 00:30:45,798 there and sells bonds to the market and 733 00:30:43,319 --> 00:30:47,720 takes the cash back okay that's a 734 00:30:45,798 --> 00:30:49,918 contractionary monetary policy so when 735 00:30:47,720 --> 00:30:52,120 the FED wants to yeah when the FED let 736 00:30:49,919 --> 00:30:54,759 me justew when the FED wants to cut 737 00:30:52,119 --> 00:30:57,119 interest rate what the FED does is an 738 00:30:54,759 --> 00:30:59,000 expansion in monetary policy which means 739 00:30:57,119 --> 00:31:01,798 it goes out there and buys bonds from 740 00:30:59,000 --> 00:31:04,159 the market and gives cash to the market 741 00:31:01,798 --> 00:31:06,038 yeah can how can the Central Banking 742 00:31:04,159 --> 00:31:08,399 assistance guarantee that some's apply 743 00:31:06,038 --> 00:31:09,798 their bonds like if they didn't have if 744 00:31:08,398 --> 00:31:12,079 their government didn't have the 745 00:31:09,798 --> 00:31:13,759 financial stability I guess the like 746 00:31:12,079 --> 00:31:16,199 United States has how would they 747 00:31:13,759 --> 00:31:18,158 guarantee that these bonds will be worth 748 00:31:16,200 --> 00:31:20,000 anything in the long well I mean there's 749 00:31:18,159 --> 00:31:21,480 you're talking about risk premium and 750 00:31:20,000 --> 00:31:25,000 that's a that's 751 00:31:21,480 --> 00:31:28,480 that's that's an an additional issue 752 00:31:25,000 --> 00:31:31,480 typically a a central banks inter 753 00:31:28,480 --> 00:31:34,159 in in in in very short duration bonds so 754 00:31:31,480 --> 00:31:36,639 there it's not the typical bond that is 755 00:31:34,159 --> 00:31:39,440 risky in many sense it's very very very 756 00:31:36,638 --> 00:31:42,519 short duration bonds treasuries very 757 00:31:39,440 --> 00:31:44,240 short duration in fact it's even less 758 00:31:42,519 --> 00:31:48,440 nowadays central banks really intervene 759 00:31:44,240 --> 00:31:50,319 in the in the overnight Market is is but 760 00:31:48,440 --> 00:31:52,278 but you're right that that countries 761 00:31:50,319 --> 00:31:54,678 that don't have a bond market a 762 00:31:52,278 --> 00:31:56,200 well-developed market have problems with 763 00:31:54,679 --> 00:31:57,360 the management of monetary policy and so 764 00:31:56,200 --> 00:31:59,240 on because they have a cretive spread 765 00:31:57,359 --> 00:32:00,599 that is moving around around as well but 766 00:31:59,240 --> 00:32:02,399 they tend to focus on the type of 767 00:32:00,599 --> 00:32:05,558 instruments that thing becomes very 768 00:32:02,398 --> 00:32:07,879 important I mean for Japan even big guys 769 00:32:05,558 --> 00:32:10,558 very big guys now they have an issue 770 00:32:07,880 --> 00:32:13,200 because they have been buying bonds very 771 00:32:10,558 --> 00:32:16,119 long duration bonds 10 year bonds and 772 00:32:13,200 --> 00:32:17,919 stuff like that and there it's a little 773 00:32:16,119 --> 00:32:19,719 trickier Market need to trust you a lot 774 00:32:17,919 --> 00:32:21,440 more if you're dealing with 10e things 775 00:32:19,720 --> 00:32:23,600 and you're dealing with a three-month 776 00:32:21,440 --> 00:32:28,840 Horizons and so 777 00:32:23,599 --> 00:32:31,398 on in other instances a um 778 00:32:28,839 --> 00:32:33,638 erh for example Chile has a situation 779 00:32:31,398 --> 00:32:36,599 like that the Central Bank itself can 780 00:32:33,638 --> 00:32:38,638 issue bonds and so those are bonds 781 00:32:36,599 --> 00:32:40,879 issued by the central banks and they 782 00:32:38,638 --> 00:32:42,158 tend to be very reliable bonds because 783 00:32:40,880 --> 00:32:43,880 these are bonds that are issuing your 784 00:32:42,159 --> 00:32:45,399 same currency so you have the currency 785 00:32:43,880 --> 00:32:48,120 to always pay the you can always print 786 00:32:45,398 --> 00:32:50,079 money and pay for those bonds you see so 787 00:32:48,119 --> 00:32:53,158 it rarely happens that there is default 788 00:32:50,079 --> 00:32:56,278 on bonds of that kind 789 00:32:53,159 --> 00:33:00,000 ER the typical bonds government bond 790 00:32:56,278 --> 00:33:01,440 that defaults is a bond that is issuing 791 00:33:00,000 --> 00:33:03,079 a currency different from the one you 792 00:33:01,440 --> 00:33:04,919 have because then you may not have the 793 00:33:03,079 --> 00:33:07,398 currency to pay for stu okay and that's 794 00:33:04,919 --> 00:33:09,799 the reason em markets run into trouble 795 00:33:07,398 --> 00:33:12,439 and things of that kind 796 00:33:09,798 --> 00:33:14,319 okay so in terms of the balance sheet of 797 00:33:12,440 --> 00:33:17,080 the Central Bank how does an open market 798 00:33:14,319 --> 00:33:18,519 operation look so if you look at the at 799 00:33:17,079 --> 00:33:20,199 the balance sheet this is an incredibly 800 00:33:18,519 --> 00:33:23,000 simplified version of the balance sheet 801 00:33:20,200 --> 00:33:25,440 of the of the FED no they have lots of 802 00:33:23,000 --> 00:33:28,798 things some more assets gold and all 803 00:33:25,440 --> 00:33:32,038 sort of stuff but in our simple economy 804 00:33:28,798 --> 00:33:34,079 the government the the fed the assets of 805 00:33:32,038 --> 00:33:36,278 the feds is they have some bonds it has 806 00:33:34,079 --> 00:33:38,519 already some bonds out there and the 807 00:33:36,278 --> 00:33:40,278 liabilities is the money they issue they 808 00:33:38,519 --> 00:33:42,480 owe that to people I mean they issue 809 00:33:40,278 --> 00:33:43,798 currency but you know but but that's 810 00:33:42,480 --> 00:33:46,159 it's a 811 00:33:43,798 --> 00:33:47,720 liability people can do things with can 812 00:33:46,159 --> 00:33:49,840 buy things with that money and so it's a 813 00:33:47,720 --> 00:33:52,919 liability so that's the way the balance 814 00:33:49,839 --> 00:33:55,638 sheet looks so when when the the FED 815 00:33:52,919 --> 00:33:59,679 decides to do an expansionary open 816 00:33:55,638 --> 00:34:03,398 market operation then what it does is it 817 00:33:59,679 --> 00:34:06,240 goes out there it IT issues an say a $1 818 00:34:03,398 --> 00:34:08,000 million expansionary open market 819 00:34:06,240 --> 00:34:10,480 operation they do it in much we get 820 00:34:08,000 --> 00:34:13,239 tickets on this but let's make it simple 821 00:34:10,480 --> 00:34:15,719 $1 million of an expansionary operation 822 00:34:13,239 --> 00:34:18,638 but they go they go out there they they 823 00:34:15,719 --> 00:34:22,078 print a million dollars and they buy a 824 00:34:18,639 --> 00:34:25,960 million dollars from the market okay and 825 00:34:22,079 --> 00:34:28,240 so at the end the balance sheet ends 826 00:34:25,960 --> 00:34:30,800 like it used to be the there's an extra 827 00:34:28,239 --> 00:34:32,719 $1 million of liabilities because now 828 00:34:30,800 --> 00:34:36,079 there's a million more of dollars 829 00:34:32,719 --> 00:34:38,039 circulating out there and but but the 830 00:34:36,079 --> 00:34:42,079 against that the Central Bank also has a 831 00:34:38,039 --> 00:34:44,878 million more of bonds Holdings 832 00:34:42,079 --> 00:34:47,320 okay so that's that's what happens with 833 00:34:44,878 --> 00:34:49,199 when so so when in an expansionary 834 00:34:47,320 --> 00:34:51,559 monetary policy the balance sheet of the 835 00:34:49,199 --> 00:34:55,239 Central Bank expands both sides expand 836 00:34:51,559 --> 00:34:58,559 by the same amount okay but expands and 837 00:34:55,239 --> 00:34:59,919 one of the big themes of recent years 838 00:34:58,559 --> 00:35:02,719 starting from the global financial 839 00:34:59,920 --> 00:35:05,320 crisis is that these balance sheets used 840 00:35:02,719 --> 00:35:07,000 to be small peanuts type things for I 841 00:35:05,320 --> 00:35:09,720 mean a trillion dollar or something like 842 00:35:07,000 --> 00:35:12,480 that for something like the the US the 843 00:35:09,719 --> 00:35:14,159 size nowadays they're much much larger 844 00:35:12,480 --> 00:35:15,719 than that because they have done so many 845 00:35:14,159 --> 00:35:17,279 operations to first get us out of the 846 00:35:15,719 --> 00:35:19,279 global financial crisis and then to get 847 00:35:17,280 --> 00:35:20,800 us out of covid and so on that these 848 00:35:19,280 --> 00:35:23,440 balance sheets are 849 00:35:20,800 --> 00:35:25,599 now an order or two orders of magnitude 850 00:35:23,440 --> 00:35:28,920 larger than they used to be 851 00:35:25,599 --> 00:35:31,440 okay but be in words they have had to do 852 00:35:28,920 --> 00:35:35,559 lots of expansionary monetary policy 853 00:35:31,440 --> 00:35:35,559 over the last couple of decades or 854 00:35:37,440 --> 00:35:43,920 so so let me talk about a little bit 855 00:35:40,838 --> 00:35:46,000 about interest rate and bond prices 856 00:35:43,920 --> 00:35:49,519 because that's the other side of this 857 00:35:46,000 --> 00:35:50,838 thing so so what is the connection 858 00:35:49,519 --> 00:35:52,199 because sometimes it's easier to 859 00:35:50,838 --> 00:35:56,440 understand things in terms of price in 860 00:35:52,199 --> 00:35:58,838 terms of bonds so suppose a bond pays 861 00:35:56,440 --> 00:36:00,920 $100 a year from now and and no coupon 862 00:35:58,838 --> 00:36:05,000 in between so if you buy a bond now for 863 00:36:00,920 --> 00:36:07,680 some price PB you get $100 a year from 864 00:36:05,000 --> 00:36:09,920 now so what is the interest rate of that 865 00:36:07,679 --> 00:36:11,480 bond that is what is the excess return 866 00:36:09,920 --> 00:36:13,358 that you get out of that or the return 867 00:36:11,480 --> 00:36:17,000 you get out of buying that 868 00:36:13,358 --> 00:36:20,159 Bond well it's going to be $100 minus 869 00:36:17,000 --> 00:36:23,679 whatever you pay today say you pay 95 870 00:36:20,159 --> 00:36:26,598 then $5 divided by your investment 871 00:36:23,679 --> 00:36:29,279 initial investment which was 95 okay so 872 00:36:26,599 --> 00:36:32,760 that's a bond that gives you know a 873 00:36:29,280 --> 00:36:34,000 little bit more than 5% in a year okay 874 00:36:32,760 --> 00:36:35,960 that's a return that's interesting so 875 00:36:34,000 --> 00:36:38,838 that's a connection between interest 876 00:36:35,960 --> 00:36:40,000 rate and prices and notice that this is 877 00:36:38,838 --> 00:36:43,279 an inverse 878 00:36:40,000 --> 00:36:46,159 relation you know when the price of a 879 00:36:43,280 --> 00:36:47,640 bond goes up the interest rate pay goes 880 00:36:46,159 --> 00:36:49,399 down because you're paying more for the 881 00:36:47,639 --> 00:36:51,559 same principle you're going to get 100 882 00:36:49,400 --> 00:36:52,760 but now you're paying more for it well 883 00:36:51,559 --> 00:36:56,039 that means the interest rate the return 884 00:36:52,760 --> 00:36:58,319 on that Bond went down 885 00:36:56,039 --> 00:37:00,000 okay conversion you can say the other 886 00:36:58,318 --> 00:37:01,759 way around the higher is the interest 887 00:37:00,000 --> 00:37:04,119 rate the lower is the price of bond of a 888 00:37:01,760 --> 00:37:05,680 bond so for example today the interest 889 00:37:04,119 --> 00:37:09,760 rate is 890 00:37:05,679 --> 00:37:11,639 5% a ER if I want to issue a bond that 891 00:37:09,760 --> 00:37:15,040 doesn't pay any coupon and I'm 892 00:37:11,639 --> 00:37:16,358 completely safe so I'm the US Treasury 893 00:37:15,039 --> 00:37:18,159 I'm going to be able to sell that bone 894 00:37:16,358 --> 00:37:20,559 for 895 00:37:18,159 --> 00:37:21,598 95 two years ago when the interest rate 896 00:37:20,559 --> 00:37:23,639 was 897 00:37:21,599 --> 00:37:26,160 Zero the fair would have been able to 898 00:37:23,639 --> 00:37:28,078 sell that bond for 899 00:37:26,159 --> 00:37:29,440 100 okay 900 00:37:28,079 --> 00:37:30,880 so there's an inverse relationship 901 00:37:29,440 --> 00:37:34,200 between the interest rate and the price 902 00:37:30,880 --> 00:37:36,720 of bonds and now I can take you back to 903 00:37:34,199 --> 00:37:38,039 my open market operation so remember 904 00:37:36,719 --> 00:37:40,480 what what I said there's another way of 905 00:37:38,039 --> 00:37:42,838 remembering sort of which way these 906 00:37:40,480 --> 00:37:44,760 signs go remember when you have an 907 00:37:42,838 --> 00:37:46,318 expansionary monetary operation I said 908 00:37:44,760 --> 00:37:49,680 the FED goes out there with a back of 909 00:37:46,318 --> 00:37:52,119 money and buys bonds from the market 910 00:37:49,679 --> 00:37:53,719 when bonds when you buy something when 911 00:37:52,119 --> 00:37:55,000 there's an enormous increase in demand 912 00:37:53,719 --> 00:37:58,078 for something what do you think happens 913 00:37:55,000 --> 00:38:00,880 to the price of that something 914 00:37:58,079 --> 00:38:03,680 goes up no for anything cars whatever it 915 00:38:00,880 --> 00:38:07,039 is if there's a lot more demand then 916 00:38:03,679 --> 00:38:10,919 prices will go up and the FED has a lot 917 00:38:07,039 --> 00:38:13,199 of cash so he can really buy large 918 00:38:10,920 --> 00:38:15,760 amount of bonds and so when the FED goes 919 00:38:13,199 --> 00:38:17,639 out there and does an expansionary open 920 00:38:15,760 --> 00:38:19,880 market operation means it goes out there 921 00:38:17,639 --> 00:38:21,879 and buys a lot of bonds the price of 922 00:38:19,880 --> 00:38:23,400 those bonds goes up and made that 923 00:38:21,880 --> 00:38:25,960 formula that means the interest rate is 924 00:38:23,400 --> 00:38:27,960 going down okay so that's another way of 925 00:38:25,960 --> 00:38:30,720 understanding how is it 926 00:38:27,960 --> 00:38:32,318 expansion open market operation lowers 927 00:38:30,719 --> 00:38:34,639 the interest rate it's because it raises 928 00:38:32,318 --> 00:38:36,639 the price of the bonds that is 929 00:38:34,639 --> 00:38:40,239 demanding and when you raise the price 930 00:38:36,639 --> 00:38:40,239 of the bonds then the interest rate goes 931 00:38:43,800 --> 00:38:51,800 down will I do this to 932 00:38:47,039 --> 00:38:53,519 you well very quickly so really the only 933 00:38:51,800 --> 00:38:55,760 thing I really care I want you to 934 00:38:53,519 --> 00:38:58,000 understand what I what I just said well 935 00:38:55,760 --> 00:39:00,480 because we're going to use it 936 00:38:58,000 --> 00:39:03,440 I want to you to understand what comes 937 00:39:00,480 --> 00:39:05,920 next ideally well but but it's okay if 938 00:39:03,440 --> 00:39:06,880 you don't understand it too well okay 939 00:39:05,920 --> 00:39:08,440 and I'm going to tell you when do you 940 00:39:06,880 --> 00:39:11,318 have to start understanding very well 941 00:39:08,440 --> 00:39:14,039 again okay for now this this is a pie in 942 00:39:11,318 --> 00:39:16,639 qu is what I'm doing here is making 943 00:39:14,039 --> 00:39:19,239 things a little bit more realistic the 944 00:39:16,639 --> 00:39:21,440 the message will be similar but it's a 945 00:39:19,239 --> 00:39:23,559 little bit more complicated okay and 946 00:39:21,440 --> 00:39:26,480 that's the reason sort of 947 00:39:23,559 --> 00:39:28,279 substantively H um I already told you 948 00:39:26,480 --> 00:39:29,960 what I wanted to tell you 949 00:39:28,280 --> 00:39:31,359 what I'm going to tell you now will give 950 00:39:29,960 --> 00:39:32,760 you a little bit more realism and 951 00:39:31,358 --> 00:39:34,358 therefore will allow you to understand a 952 00:39:32,760 --> 00:39:36,720 little bit 953 00:39:34,358 --> 00:39:39,159 better a technical description of 954 00:39:36,719 --> 00:39:40,358 monetary policy or something like that 955 00:39:39,159 --> 00:39:43,078 so in 956 00:39:40,358 --> 00:39:45,000 practice you know in the economy I just 957 00:39:43,079 --> 00:39:48,240 describe you had sort of households and 958 00:39:45,000 --> 00:39:50,079 firms and the central bank but in 959 00:39:48,239 --> 00:39:52,318 practice there are lot of financial 960 00:39:50,079 --> 00:39:54,680 intermediaries okay and in financial 961 00:39:52,318 --> 00:39:56,358 intermed the most prominent of them for 962 00:39:54,679 --> 00:39:58,519 especially for monetary policy are the 963 00:39:56,358 --> 00:39:59,719 banks and there are certain Banks 964 00:39:58,519 --> 00:40:02,318 actually they're even more important 965 00:39:59,719 --> 00:40:04,598 than others but banks are financially 966 00:40:02,318 --> 00:40:07,519 intim intimidates they take money from 967 00:40:04,599 --> 00:40:09,039 someone or deposit from someone and lend 968 00:40:07,519 --> 00:40:11,920 it to someone else or buy some 969 00:40:09,039 --> 00:40:13,960 instruments okay so so they intermediate 970 00:40:11,920 --> 00:40:16,559 the funds of somebody that wants to save 971 00:40:13,960 --> 00:40:19,119 on in the bank a deposit in a deposit 972 00:40:16,559 --> 00:40:19,920 account or something and they they lend 973 00:40:19,119 --> 00:40:22,200 that 974 00:40:19,920 --> 00:40:28,280 money effectively in the name of the 975 00:40:22,199 --> 00:40:32,000 other person to H someone else okay so 976 00:40:28,280 --> 00:40:35,519 Banks do two things to the model I just 977 00:40:32,000 --> 00:40:36,719 described the first is that they produce 978 00:40:35,519 --> 00:40:38,318 money as 979 00:40:36,719 --> 00:40:40,039 well 980 00:40:38,318 --> 00:40:43,279 okay 981 00:40:40,039 --> 00:40:45,599 because ER money is made of currency 982 00:40:43,280 --> 00:40:48,680 which is is issued by the central bank 983 00:40:45,599 --> 00:40:51,000 but it's also made of a checkable 984 00:40:48,679 --> 00:40:53,519 deposits if you have a a checking 985 00:40:51,000 --> 00:40:56,639 account something you can have a debit 986 00:40:53,519 --> 00:40:59,880 card against or something like that then 987 00:40:56,639 --> 00:41:02,078 then that's money for you okay if you 988 00:40:59,880 --> 00:41:07,079 deposit in a bank in a checking 989 00:41:02,079 --> 00:41:09,280 account that's money okay and so when 990 00:41:07,079 --> 00:41:12,119 Banks the liabilities of banks the 991 00:41:09,280 --> 00:41:13,599 deposits is part of money it's something 992 00:41:12,119 --> 00:41:15,160 you can use for transactions you can 993 00:41:13,599 --> 00:41:17,559 write checks you can use your debit card 994 00:41:15,159 --> 00:41:20,960 and stuff like that okay so that's the 995 00:41:17,559 --> 00:41:22,318 first thing that Banks do okay the other 996 00:41:20,960 --> 00:41:23,920 thing the banks 997 00:41:22,318 --> 00:41:27,400 do 998 00:41:23,920 --> 00:41:29,760 is they themselves have a deposit 999 00:41:27,400 --> 00:41:34,480 account at the Central 1000 00:41:29,760 --> 00:41:37,359 Bank okay so they themselves take part 1001 00:41:34,480 --> 00:41:39,240 of the deposits they take the deposits 1002 00:41:37,358 --> 00:41:41,719 part of the deposit they lend to other 1003 00:41:39,239 --> 00:41:43,959 people another part they buy financial 1004 00:41:41,719 --> 00:41:46,480 instruments Bond and stuff like that in 1005 00:41:43,960 --> 00:41:49,440 this economy would be only bonds and the 1006 00:41:46,480 --> 00:41:53,480 other part smaller part 10% or something 1007 00:41:49,440 --> 00:41:55,960 like that they deposit at the central 1008 00:41:53,480 --> 00:41:58,358 bank that deposit at the central bank is 1009 00:41:55,960 --> 00:42:01,358 called Reserves 1010 00:41:58,358 --> 00:42:04,358 okay so when you he the word reserves of 1011 00:42:01,358 --> 00:42:07,199 the banking sector this is the deposits 1012 00:42:04,358 --> 00:42:10,639 of the banks at the Central 1013 00:42:07,199 --> 00:42:11,960 Bank okay and that's that's also 1014 00:42:10,639 --> 00:42:13,719 liability for the Central Bank the 1015 00:42:11,960 --> 00:42:15,440 central bank is holding that deposit of 1016 00:42:13,719 --> 00:42:17,598 the banks it's not the central bank's 1017 00:42:15,440 --> 00:42:19,599 money it's the it's the bank's money 1018 00:42:17,599 --> 00:42:22,318 okay and they're holding it there it's a 1019 00:42:19,599 --> 00:42:22,318 liability as 1020 00:42:22,480 --> 00:42:27,960 well so now if you look at how the 1021 00:42:25,760 --> 00:42:30,680 balance sheets look 1022 00:42:27,960 --> 00:42:33,679 our central bank now has more things he 1023 00:42:30,679 --> 00:42:35,960 has assets going to be Bonds in this 1024 00:42:33,679 --> 00:42:38,480 economy this only thing you can have but 1025 00:42:35,960 --> 00:42:40,960 now it will have the currency that had 1026 00:42:38,480 --> 00:42:42,920 before and in liabilities but also will 1027 00:42:40,960 --> 00:42:46,720 have the Reserves the deposits of the 1028 00:42:42,920 --> 00:42:46,720 banks themselves 1029 00:42:48,880 --> 00:42:54,680 okay okay and this is called this stuff 1030 00:42:51,800 --> 00:42:56,519 here is called central bank money in 1031 00:42:54,679 --> 00:42:57,799 contrast it is called Central Bank it 1032 00:42:56,519 --> 00:42:59,800 has so many names 1033 00:42:57,800 --> 00:43:01,280 it's called central bank money high 1034 00:42:59,800 --> 00:43:04,599 power 1035 00:43:01,280 --> 00:43:07,440 money some other name have some but but 1036 00:43:04,599 --> 00:43:09,240 but he has several names and what is I I 1037 00:43:07,440 --> 00:43:11,679 like the name central bank money because 1038 00:43:09,239 --> 00:43:13,279 that's in contrast with this kind of 1039 00:43:11,679 --> 00:43:16,000 money it's the money that the banking 1040 00:43:13,280 --> 00:43:18,119 sector produces the checkable deposits 1041 00:43:16,000 --> 00:43:20,599 okay so this is the money produced by 1042 00:43:18,119 --> 00:43:22,920 the central bank and then the and then 1043 00:43:20,599 --> 00:43:25,800 through deposits the financial system 1044 00:43:22,920 --> 00:43:28,880 the banks themselves produce more 1045 00:43:25,800 --> 00:43:32,240 money so The Total Money in the system 1046 00:43:28,880 --> 00:43:35,318 is much more than the central bank money 1047 00:43:32,239 --> 00:43:39,199 because deposits is a big thing you 1048 00:43:35,318 --> 00:43:43,119 know this is much larger than that in 1049 00:43:39,199 --> 00:43:46,159 practice okay good how does this change 1050 00:43:43,119 --> 00:43:47,400 our mold not really much and so so again 1051 00:43:46,159 --> 00:43:50,000 that's the reason I don't care too much 1052 00:43:47,400 --> 00:43:53,119 if you understand these last two slides 1053 00:43:50,000 --> 00:43:56,559 so let me rederive what we 1054 00:43:53,119 --> 00:43:59,599 have with this approach with with this 1055 00:43:56,559 --> 00:44:01,839 this uh extension so money demand is the 1056 00:43:59,599 --> 00:44:03,079 same as it used to be what happens is 1057 00:44:01,838 --> 00:44:04,719 you're going to demand it in the form of 1058 00:44:03,079 --> 00:44:06,119 currency or checking accounts or 1059 00:44:04,719 --> 00:44:09,799 something like that but but the total 1060 00:44:06,119 --> 00:44:15,240 money demand is exactly as it used to 1061 00:44:09,800 --> 00:44:16,920 be Banks typically hold a share of a and 1062 00:44:15,239 --> 00:44:18,919 assume for now that there's no currency 1063 00:44:16,920 --> 00:44:20,440 so everything is check is deposit 1064 00:44:18,920 --> 00:44:23,800 otherwise you get a more complicated 1065 00:44:20,440 --> 00:44:26,200 formula okay so no one holds cash which 1066 00:44:23,800 --> 00:44:28,318 probably quite realistic nowadays you so 1067 00:44:26,199 --> 00:44:30,439 everyone has a checking account and 1068 00:44:28,318 --> 00:44:33,239 that's it 1069 00:44:30,440 --> 00:44:36,599 okay 1070 00:44:33,239 --> 00:44:40,558 so the banks 1071 00:44:36,599 --> 00:44:42,599 typically hold for regulatory reasons a 1072 00:44:40,559 --> 00:44:45,599 share of their Deposit they have a 1073 00:44:42,599 --> 00:44:48,039 minimum for regulatory reasons a minimum 1074 00:44:45,599 --> 00:44:50,400 share of the deposit they have that they 1075 00:44:48,039 --> 00:44:52,239 need to hold in the form of reserves 1076 00:44:50,400 --> 00:44:55,960 okay and I'm going to call that a fixed 1077 00:44:52,239 --> 00:44:58,879 fraction Theta so if all the money is 1078 00:44:55,960 --> 00:45:01,960 held in the form of the deposits then 1079 00:44:58,880 --> 00:45:05,160 Theta which is a number like 0.1 say 1080 00:45:01,960 --> 00:45:08,760 times the deposits which is money demand 1081 00:45:05,159 --> 00:45:10,639 is equal to the reserves at the is equal 1082 00:45:08,760 --> 00:45:11,520 to the central the demand for central 1083 00:45:10,639 --> 00:45:13,679 bank 1084 00:45:11,519 --> 00:45:16,119 money this is the demand for central 1085 00:45:13,679 --> 00:45:17,960 bank money because is this are the N 1086 00:45:16,119 --> 00:45:20,760 these are the reserves that the banks 1087 00:45:17,960 --> 00:45:22,280 want to have at the central bank so the 1088 00:45:20,760 --> 00:45:24,760 demand they they want to have this 1089 00:45:22,280 --> 00:45:28,480 amount of deposits at the central bank 1090 00:45:24,760 --> 00:45:30,319 this what we call HD it's Theta time m 1091 00:45:28,480 --> 00:45:31,960 and so now rather than M what the 1092 00:45:30,318 --> 00:45:34,039 Central Bank controls really because 1093 00:45:31,960 --> 00:45:36,760 it's the only thing can really control 1094 00:45:34,039 --> 00:45:39,558 is the money that it issues issues which 1095 00:45:36,760 --> 00:45:42,319 is the central bank money so R supplying 1096 00:45:39,559 --> 00:45:43,920 M which used to be currency now m is a 1097 00:45:42,318 --> 00:45:46,159 bigger thing because has deposits and 1098 00:45:43,920 --> 00:45:48,240 all sort of stuff but the central bank 1099 00:45:46,159 --> 00:45:50,480 is the one that controls how much high 1100 00:45:48,239 --> 00:45:53,639 power money how much central bank money 1101 00:45:50,480 --> 00:45:57,559 it issues and we're going to call that 1102 00:45:53,639 --> 00:45:59,639 H okay so if we go back to my balance 1103 00:45:57,559 --> 00:46:01,160 sheet here the Central Bank cannot 1104 00:45:59,639 --> 00:46:03,039 control total money because it cannot 1105 00:46:01,159 --> 00:46:06,399 control the amount of checkable deposits 1106 00:46:03,039 --> 00:46:08,639 in the economy but it can control this 1107 00:46:06,400 --> 00:46:10,920 money here and since we have no currency 1108 00:46:08,639 --> 00:46:14,279 my example it really can control how 1109 00:46:10,920 --> 00:46:16,039 much supply of reserves it can do okay 1110 00:46:14,280 --> 00:46:17,400 and so now we have a demand for Reserve 1111 00:46:16,039 --> 00:46:20,199 which is just proportional to money 1112 00:46:17,400 --> 00:46:22,960 demand equal to some fixed amount H 1113 00:46:20,199 --> 00:46:24,719 which is the supply of high power money 1114 00:46:22,960 --> 00:46:27,318 by the central bank and then the 1115 00:46:24,719 --> 00:46:28,919 equilibrium looks exactly 1116 00:46:27,318 --> 00:46:32,318 like before it's going to be some 1117 00:46:28,920 --> 00:46:36,119 remember before we have m equal to 1118 00:46:32,318 --> 00:46:39,800 Dollar y i now we're saying it's not M 1119 00:46:36,119 --> 00:46:43,000 it's Theta times M really no because 1120 00:46:39,800 --> 00:46:47,200 it's a fraction only of Total Money okay 1121 00:46:43,000 --> 00:46:48,760 has to be equal to a money demand it's 1122 00:46:47,199 --> 00:46:50,279 not Total Money demand it's the money 1123 00:46:48,760 --> 00:46:52,640 demand that ends up being demand for 1124 00:46:50,280 --> 00:46:55,599 central bank money because Total Money 1125 00:46:52,639 --> 00:46:58,039 demand is the checkable checking 1126 00:46:55,599 --> 00:47:00,440 account that leads to a demand for 1127 00:46:58,039 --> 00:47:03,000 central bank money by the Banks which is 1128 00:47:00,440 --> 00:47:04,358 Theta times those deposits it's not the 1129 00:47:03,000 --> 00:47:05,838 full Deposit they don't Deposit they 1130 00:47:04,358 --> 00:47:07,480 don't take all the deposit and deposit 1131 00:47:05,838 --> 00:47:09,279 at Central Bank they say only 10% of 1132 00:47:07,480 --> 00:47:12,760 those deposit will keep them at the 1133 00:47:09,280 --> 00:47:15,720 central bank so $100 in deposit if 30 is 1134 00:47:12,760 --> 00:47:17,640 point1 $100 in deposit leads to a demand 1135 00:47:15,719 --> 00:47:20,439 for reserves that mean for deposits by 1136 00:47:17,639 --> 00:47:23,838 the bank and the Central Bank of 1137 00:47:20,440 --> 00:47:26,280 $10 okay and that is the thing that the 1138 00:47:23,838 --> 00:47:28,838 central bank can control very well it's 1139 00:47:26,280 --> 00:47:31,280 a m the is the demand that comes to me 1140 00:47:28,838 --> 00:47:34,400 the central bank is $10 and I decide 1141 00:47:31,280 --> 00:47:35,720 whether we do $10 or not you we can do 1142 00:47:34,400 --> 00:47:38,680 five and then we're going to have the 1143 00:47:35,719 --> 00:47:41,598 interest rate sort out five to be in 1144 00:47:38,679 --> 00:47:43,598 equilibrium so it's if if if the banking 1145 00:47:41,599 --> 00:47:46,000 sector wanted 10 and I'm only going to 1146 00:47:43,599 --> 00:47:48,680 supply five then something the interest 1147 00:47:46,000 --> 00:47:51,280 rate is going to have to rise so that 1148 00:47:48,679 --> 00:47:54,679 deposits you know decline less demand 1149 00:47:51,280 --> 00:47:57,280 for money and and the and the final 1150 00:47:54,679 --> 00:47:59,118 demand that gets to me is five not 10 1151 00:47:57,280 --> 00:48:01,119 but the mechanism is exactly the same I 1152 00:47:59,119 --> 00:48:03,240 know this this can be a little confusing 1153 00:48:01,119 --> 00:48:06,160 but the mechanism exactly the same it's 1154 00:48:03,239 --> 00:48:09,399 just this just illustrates it makes I 1155 00:48:06,159 --> 00:48:09,399 mean this this is important 1156 00:48:09,800 --> 00:48:14,680 because it's institutionally important 1157 00:48:12,440 --> 00:48:16,200 more than conceptually important because 1158 00:48:14,679 --> 00:48:17,440 this is the market where really the 1159 00:48:16,199 --> 00:48:21,838 interest rate is 1160 00:48:17,440 --> 00:48:24,000 set okay so this I'm doing next time 1161 00:48:21,838 --> 00:48:25,920 that market the market for reserves 1162 00:48:24,000 --> 00:48:27,280 really because what the banks do is they 1163 00:48:25,920 --> 00:48:29,440 want Reserves 1164 00:48:27,280 --> 00:48:31,280 okay deposit at the central bank that 1165 00:48:29,440 --> 00:48:33,639 market for reserves the interest rate in 1166 00:48:31,280 --> 00:48:36,200 that market for reserves is called the 1167 00:48:33,639 --> 00:48:37,960 federal funds rate and it's called the 1168 00:48:36,199 --> 00:48:40,519 federal funds rate because the Federal 1169 00:48:37,960 --> 00:48:42,440 Reserves controls that rate so when the 1170 00:48:40,519 --> 00:48:44,079 FED when when there is a meeting by the 1171 00:48:42,440 --> 00:48:45,440 fed or a policy announcement that tell 1172 00:48:44,079 --> 00:48:48,760 you that the the FED has increased the 1173 00:48:45,440 --> 00:48:50,159 rate by 50 basis points it means it has 1174 00:48:48,760 --> 00:48:54,400 increased the interest rate in that 1175 00:48:50,159 --> 00:48:56,159 market by 50 basis points okay so the 1176 00:48:54,400 --> 00:48:57,920 interest rate that the Central Bank 1177 00:48:56,159 --> 00:49:01,078 controls corly is called the federal 1178 00:48:57,920 --> 00:49:02,920 funds rate and the federal funds rate is 1179 00:49:01,079 --> 00:49:05,280 that market is market for reserve for 1180 00:49:02,920 --> 00:49:08,280 high power money so all the operations 1181 00:49:05,280 --> 00:49:11,000 happen there they don't participate in 1182 00:49:08,280 --> 00:49:13,040 the deposit Market or anything they 1183 00:49:11,000 --> 00:49:15,000 participate in that market which every 1184 00:49:13,039 --> 00:49:17,639 night is a is a Hu huge number of 1185 00:49:15,000 --> 00:49:19,239 transactions every night because I put 1186 00:49:17,639 --> 00:49:20,798 all the banks together but what happens 1187 00:49:19,239 --> 00:49:22,199 every night is some banks have more 1188 00:49:20,798 --> 00:49:24,318 reserves than they need some other banks 1189 00:49:22,199 --> 00:49:26,358 have less reserves than they need so 1190 00:49:24,318 --> 00:49:28,039 they supply and demand within the 1191 00:49:26,358 --> 00:49:29,558 banking sector for for reserves and 1192 00:49:28,039 --> 00:49:31,920 there's an interest rate that tends to 1193 00:49:29,559 --> 00:49:33,680 equilibrate if too many banks are short 1194 00:49:31,920 --> 00:49:34,880 reserves then there's going to be lots 1195 00:49:33,679 --> 00:49:36,639 of demand for reserve and interest rate 1196 00:49:34,880 --> 00:49:38,920 is going to tend to go up If the Fed 1197 00:49:36,639 --> 00:49:40,838 doesn't want that interest rate to go up 1198 00:49:38,920 --> 00:49:42,920 then what it will do overnight it will 1199 00:49:40,838 --> 00:49:44,759 go there and inject reserves into the 1200 00:49:42,920 --> 00:49:47,519 system high power money so the interest 1201 00:49:44,760 --> 00:49:50,160 rate in that market comes down okay and 1202 00:49:47,519 --> 00:49:51,880 that's the way the FED operates that's 1203 00:49:50,159 --> 00:49:53,920 the way it controls it participates in 1204 00:49:51,880 --> 00:49:57,200 that market controls the amount of high 1205 00:49:53,920 --> 00:50:00,079 power money which regulates the rate in 1206 00:49:57,199 --> 00:50:02,879 the resarch market and here it's only 1207 00:50:00,079 --> 00:50:06,798 you know and then so here you have sort 1208 00:50:02,880 --> 00:50:09,240 of the major Banks participating here 1209 00:50:06,798 --> 00:50:10,759 and and and then this leaks into the 1210 00:50:09,239 --> 00:50:13,479 other interest rates in the economy to 1211 00:50:10,760 --> 00:50:15,760 into deposit rates to to bond rates and 1212 00:50:13,480 --> 00:50:18,679 so on but but the real rate they control 1213 00:50:15,760 --> 00:50:21,040 the rate that they control most directly 1214 00:50:18,679 --> 00:50:22,318 is that rate here okay and that's the 1215 00:50:21,039 --> 00:50:23,440 reason I wanted to give you a little bit 1216 00:50:22,318 --> 00:50:26,239 of 1217 00:50:23,440 --> 00:50:29,039 institutional I mean to add complexity 1218 00:50:26,239 --> 00:50:29,039 so we could get 1219 00:50:29,358 --> 00:50:34,159 to so you could get to this word federal 1220 00:50:32,039 --> 00:50:36,719 funds rate because that's what you're 1221 00:50:34,159 --> 00:50:38,480 going to read in the newspapers the FED 1222 00:50:36,719 --> 00:50:39,798 increase the federal funds Target is 1223 00:50:38,480 --> 00:50:41,159 going to say because they target they 1224 00:50:39,798 --> 00:50:42,719 cannot guarantee it's going to be that 1225 00:50:41,159 --> 00:50:44,318 they target an interest rate and 1226 00:50:42,719 --> 00:50:49,000 typically they give you a range it's a 1227 00:50:44,318 --> 00:50:51,119 very narrow range okay you let me just 1228 00:50:49,000 --> 00:50:55,519 conclude by showing you how that rate 1229 00:50:51,119 --> 00:51:00,119 has looked in the US recently okay and I 1230 00:50:55,519 --> 00:51:02,679 finish here so here here is before covid 1231 00:51:00,119 --> 00:51:04,798 okay H the interest rate the Fed was 1232 00:51:02,679 --> 00:51:06,598 already hik in interest rate it had 1233 00:51:04,798 --> 00:51:08,559 overdone it there so it was beginning to 1234 00:51:06,599 --> 00:51:10,760 lower interest rate and then covid came 1235 00:51:08,559 --> 00:51:13,000 boom and they cut interest rate very 1236 00:51:10,760 --> 00:51:14,160 aggressively the this is the maximum 1237 00:51:13,000 --> 00:51:15,639 they can cut it too and we're going to 1238 00:51:14,159 --> 00:51:18,078 talk about that briefly in the next to 1239 00:51:15,639 --> 00:51:20,159 zero you cannot go below zero you cannot 1240 00:51:18,079 --> 00:51:22,079 pay negative interest rate because then 1241 00:51:20,159 --> 00:51:24,279 I don't demand money I don't demand 1242 00:51:22,079 --> 00:51:26,318 bonds why should I hold a bond that pays 1243 00:51:24,280 --> 00:51:28,280 me a negative interest rate when cash 1244 00:51:26,318 --> 00:51:30,318 pays zero always zero I can always keep 1245 00:51:28,280 --> 00:51:31,640 it under the mattress and and and I 1246 00:51:30,318 --> 00:51:33,798 don't pay in negative so the interest 1247 00:51:31,639 --> 00:51:35,199 rate the lowest can be zero and you see 1248 00:51:33,798 --> 00:51:36,960 that they they did the maximum they 1249 00:51:35,199 --> 00:51:39,039 could in terms of cutting interest rate 1250 00:51:36,960 --> 00:51:40,559 they went to zero effectively zero and 1251 00:51:39,039 --> 00:51:42,000 now they have been trying to catch up 1252 00:51:40,559 --> 00:51:44,000 because inflation is very high and so 1253 00:51:42,000 --> 00:51:46,039 they're trying to to hike interest rate 1254 00:51:44,000 --> 00:51:48,039 and you see how what they're doing okay 1255 00:51:46,039 --> 00:51:50,119 well all those interventions happen in 1256 00:51:48,039 --> 00:51:52,480 the reserve Market that's what where 1257 00:51:50,119 --> 00:51:56,039 this is that's the rate is in that 1258 00:51:52,480 --> 00:51:59,679 market over okay okay so I think we're 1259 00:51:56,039 --> 00:52:02,960 meeting on Tuesday next week uh I think 1260 00:51:59,679 --> 00:52:02,960 that's the plan
